Aug 16 (Reuters) - Emerging market stocks gained on Friday for the first time in six sessions, helped by hopes of further stimulus in China, a factor which also helped developing world currencies hold their ground against the dollar.

China’s state planner said it would roll out a plan to boost disposable income and spur consumption in the world’s second-largest economy, helping the benchmark Shanghai SE Composite index and the blue-chip Shanghai Shenzhen CSI 300 to rise 0.3% and 0.5% respectively.

The sentiment played into a 0.3% rise seen in MSCI’s developing world stocks index, with the benchmark on track to post gains for only the second time in 18 trading days.

Morten Lund, an analyst at Nordea Markets, said the stimulus would also benefit currencies of countries closely linked with China’s supply chain, especially those in Asia, though the possibility of a weaker yuan had to be kept in mind.

“We think USD/CNY is an extremely important sentiment gauge ... if it goes beyond 7.3 (yuan per dollar), we will go from a risk-off situation to a complete panic!,” Lund said.
